A XeCl-excimer laser (308 nm) was used to generate microscopic plasma from the paper coating, and delayed detection of silicon and calcium atomic emission line intensities was used as a measure of mass vaporized. Macroscopic areas typically 10 &#215; 10 mm<SUP>2</SUP> at a spatial resolution of 250 &#956;m were studied. With a single laser pulse (0.2 mJ of energy), about 2 ng of coating from a volume of 30 &#956;m in diameter and 2 &#956;m in depth was vaporized. The method seems to be useful for characterization of multilayer coatings.",
